CONNECTER FOR TRAIN PEPES Application filed September 25, 1920, SerialNo. 412,647. Renewed September 22, 1931.

My invention relates to automatic connecters for train pipes, normallyforming three hose connections Jfor passenger cars and y a single hose.or two hose connection only for freight cars.

The main purpose of my invention is to position the connecter head whennot in use by means which effectively ceases to function Y in use,leaving the head untrammeled by itin accommodation to the position andmovement of a mating head.

A further purpose is to mount the connecter head upon a-ca'rrier,preferably in the viorm of a yoke held lat a distance behind thehead'against the rear of the supporting bracket by the buffer spring anddirected to its normal position in disuse by engagement with the racket.

A-further purpose is to free the head from its directional control bythe bracket so that vit can swing in all directions when engagement withanother head compresses the buffer spring.

A further purpose is to maintain a guiding connection between thecarrier and bracket in all positions of the head so that bufferspringretraction of the carrier will seat it reliably against the stop(bracket) which positions it normally.

A further purpose is to make the buier yspring and tie rod for theconnecter insertible and removable from the bracket at the 'rear ofthebracket without change or movement of the tie rod pin. p'

A further purpose is to make the train pipe terminals themselvesadjustable in their eX- ten'sioii from the head and at the same timeremovable through the rear of the head Jfor replacement of parts withoutuncoupling the train. K

Further purposes will' appear in the speciication and in the claims.

Many inventors have attempted to sup Jort train pipe'connecter's so thattheir heads s all be in position to mate with corresponding connecterheads as the cars come together but shall be tree to move laterally withmovement of the cars about curves and vertically to interfit with headsofother connectors notwithstanding dit'ference ot heights of theconnecters of cars. i

That success in this has-been but partial has been due, to variouscauses, among which may be `mentioned rigid limitation of the range ofmovement'of the head within the narrowlimits, looseness at all times inthe effort to giveplay, the use of rigid guides for y the path ofcompression and retraction,

swinging the heads about points too close to them and using means toposition the heads normally in disuse which interferes with properflexibility in use.

I have discovered a new form of articulation for the head by which itsposition in disuse is determined by a'joint between the direct supportfor the head and the bracket by which it is connected with the car. Thisjoint is made whenthe head is in its foremost position and is releasedby rearward move* ment of the head under pressure from the 'Y matinghead of another car. When the joint is released, the head is free tomove freely about a pivot point supported by the bracket so that ,it maylift or lower to complete the "engagement with the mating head and'mayturn to either side to accommodate track Curvesfm positioning'joint,I-providea guide to maintainl effective connection between thel head andbracket and to direct the head inret-racting movement, insuringaccurateseating of the parts infdnisuse.A I

I have found further that the train pipe 'terminals carrying means vforadjustment of theirnormal` projection, may be inserted and withdrawnfromgthe rear of a head by which they are supported so thatreplacementsmay be made withoutuncoupling the cars and any j terminalmay be adjusted in position to in- 'y crease. the .extent of projectionin case of a vworn or faulty head.

Describing the construction shown by way ofillustration and not inlimitation The cast or forged bracket is supported from v'anyliixedicarmembensuch as coupler 16 by suitable 'bolts 17 and any play is taken` upby one or more transverse Wedges 18. The bracketris split at 19 toprovide spring so that the divided parts may grip the member-1'ritil-cr'htly` and is flanged for additional strength, here along thefront at 20;

or'derto give'room for the support of the head 21 at a suitabledistancein advance ofthe bracketfiind it desirableto'slope the Y bracketdownwardlyV and Arearwardly to the Blockf22fllhisfblock is speciallysuited to afford a seat or joint.

Thefeet are held to the heads bybolts 39. j

By these or similarconnections capable of performing the intendedfunctions the head vv1s firmly supported from a carrier mostconveniently made as a yoke which seats against `the rear of thebracketVwhen invitsfo'rward position (on disuse) but which in use is forcedbackwardly free fromk the seat and which cooperateswith the brackettomaintain operative relations between the `carrier and bracket. Asaresult of this cooperation, through the pin and side slots thecarrier isreturned to its seatl against the bracket as soon as the pressure fromthe opposing head is reieased. 1 Y. s

The mechanism which I show for normally maintaining thecarrier Vfaceresiliently in contact with the back face of the bracket comprises a tierod 40 anda buffer spring 41. The tie rod has anjeye 42 engaging thehook 28, at 4one' end and is threaded at the other end ,as at 43. Thebuffer spring isheld in place under compression by atie rod nut V44carrying a flange A45V. The eye is loose enough upon the hook to permitit to be placed and removed easily and to permit movement of the rodfreely in all directions.

In assemblage of these parts the eye of the tie rod is passed overthehook, the Ybuffer spring and washer areputfin place'andrtlie tie rod nutis screwed up to givethe desired initial tension. t i j By theconstruction described the tie rod and buffer spring can movein anydirection vertically or laterally or to anyy extent that the loosenessof the hookand eye connection for lateral movement may contemplate andrearward pressure upon the head immediately releases the face 24 lof thecarrier r(yoke) from its seat lagainst the'rear face of the bracket; sothat the carrier (yoke) is free to swing vertically` about the pins 26and horizontally to any extent permitted by the lost between the sidesof the carrier and guiding con-tact with the pins 26 so that the ivvvill greturn the carrier reliably to its initial position ywhenpressure upon the head is' h fig movement'of the `(whatever position in,Y esei'pinso'ceupy-f)lwillaccommodite awideange"fofL'verticaladjustment to meet connecter yheadsoff'dierenjtheights on thej adjoiningoy =`c'ars-,ffithe1extentofsiangular movement of the carrier requiredfforwany wallsof the-slots46 maintain adjustment being well Within control of the designer throughselection of the distance from'the pins 26 to the vfront face of theconnecter head. j j

. Horizontal adjustment of the connecter heads to accommodate curves isalso well within the controlof the designer by curving or sloping orotherwise'relieving the side faces 47 of the bracket block so as toreduce the width of the block as it extends forwardly, or by flaring ofthe lugs 3l, 32 and prongs 83,34 as they extend forwardly or by both ofthese means. I-have preferred to illustrate the tapering of the blockalone, which proves suiiicientfor the purpose.

The head 2l is supported from the bracket by the carrier and held toposition by the buffer mechanism, entirely independently of the positionof the connecter train pipe terminal or terminals carried by the head,with the'result that any adjustment of the train pipe terminalslongitudinally adjusts them with respect to the coupling or other fixedpart ofthe train, makes it possible to extend the distance at whichsealing contact will -take place beyond a worn or improperly placedhead. This adjustment can be made while the cars are coupled. At thesame time that I provide for such an adjustment I introduce the entiretrain pipe terminal connection within the head from the rear, so that .afaulty train pipe terminal may be withdrawn and a new gasket or a newterminal may be put in its place without breaking the coupling with theadjoining car, greatly facilitating the change and making' it' possibleto make the change without shifting.

- The train pipes are shown'at 48 as three in number, the usual numberfor passenger cars, though my invention is suitable also for the singletrain pipe connection for freight cars. The pipe couplings are shown atand are threaded upon terminals 50 carrying gaskets 51. The terminalsslide within cylindrical passages 52 extending through the head and areprovided with rearwardly-facing shoulders at 58 to receive Athe forwardthrust of expansile springs 54, whose rearward thrust is taken bycollars 56. The collars present forwardly facing surfaces and are rigidwith respect to the head.

If nowk the collars 56 be-integral with the head, as may be the caseand'isshown in my U. S. Patent No. 1,660,766 granted Februar;7 28, 1928,the train pipe terminal can not .be removed except through the front,requiring the disconnectionA of the cars, if they be coupled,rand themoving of one of the cars. By making the collars56 removable from therear, I canv make the entire train pipe minals removable rearwardly withthem. Accordingly I form these collars 56 as rings removable rearwardlyfrom the head and most desirably screwed in them at 57 by he wrenchholds 58. The inner surfaces 59 of the rings allow the terminals toslide through them, permitting the terminals to compress the springs 54and thus yield longitudinally under pressure of the opposing terminals.

Nut-s 60 afford adjustment for the normal compression of the springs 54and, correspondingly, of the normal extension of the gaskets beyond theface of the head, so that the gaskets can be adjusted separately to any.desired initial projection from the head. This makes it possible tocorrect for distortion, wear or faulty placing of the head so as toalign the gaskets in approximately the plane desired notwithstanding theresultant faulty head position. Y

The train pipe couplings 49 are threaded upon the rear of the terminalsand act as lock nuts to maintain the nuts 60 in adjusted positions.

I recognize that, in view of my disclosure herein, others skilled in theart will see many ways in which the invention disclosed may be carriedout, varied to avoid appearance of infringement or to suit thepreference of the designer, and purpose including herein all such forms'as come within the fair spirit and scope of my claims.
